The first statement relates to the To: field; the second relates to authentication of the identity of the server to which the browser connects. These elements are orthogonal and should not be conflated. As an example, if a BOSH connection manager is configured to route stanzas to domains other than its own, a browser can use a BOSH connection manager to send XMPP stanzas to any XMPP user. Authenticating the BOSH connection manager (e.g. via TLS) imposes no restriction whatsoever on who can be "called" via Jingle using that BOSH connection manger. That restriction would only be implemented within the BOSH connection manager, *not* within the browser.
